What is an Auto OBD2 Reader?

An auto OBD2 reader, also known as an OBD2 scanner or diagnostic code reader, is an electronic device that connects to your car’s onboard diagnostic (OBD) port. This port, standardized in 1996 for all vehicles sold in the United States, allows access to the vehicle’s computer system and the data it collects. Using an auto OBD2 reader, you can retrieve diagnostic trouble codes (DTCs), which are codes that indicate specific malfunctions within the vehicle’s systems.
